The game has become a race to play Zen Cartman and lag the enemy out while you've got a wave built up. This is seriously destroying the experience, smaller bugs don't seem to go away, but at least that can be worked around, this is embarrassing, and needs to be disabled.

You can't just leave this be for a month waiting for the next patch, something needs to be done quickly, and the best option would be to outright disable the card if possible. Most other PvP oriented games will outright disable units/characters/cards/etc immediately, and so I guess you can take this as a suggestion.
